Question from a Hobbit n00b
by Einar.Eliassen＠ergo.no 28 Apr '06

28 Apr '06

Hello list I'm looking for a way to monitor thin clients. Several thousand thin clients. The most important information I need to gather is: - is the client online ? - is the client running citrix client ? I would like to get this graphed. One graph for online clients and one graph for how many clients are running the citrix client. I should also be able to collect this information on demand. Is this possible with Hobbit ? Regards, Einar Eliassen

[hobbit] I'm starting to look at setting up 'propr' monitoring for my production SAP environment, and wonder if anyone else is playing with HACMP clusters
by KauffmanT＠nibco.com 27 Apr '06

27 Apr '06

That's pretty much it - except that this started as an HACMP 2.1 cluster and keeps getting upgraded as it moves to new hardware - so we're still doing IPAT and don't have either a persistent IP address or IP aliasing to keep the boot address around. I get more time to look at this next week - right now I've got a ton and a half (7.6 TB) of disk data to schlep around; I also wear the storage admin (and, for that matter, the TSM admin) hat here and we've a model 800 ESS being replaced by a DS-8100 over the next 5 days. I just wanted to kick the question off and start some ideas floating around internally. Thanks!

Then you set up a persistent IP - ( if your running HACMP 5.x this is standard) that you use for each LPAR. Then in you resource startup you enable reporting ( you will need to spoof you hostname on the reports) and in you resource shutdown scripts disable the reporting for this resource although you may want to send a report that you are going down to Hobbit this could be a custom report of status on your screen. The node up and down could spawn updates along with the hacmp.out log file or a subset. You could also make your reporting HACMP aware and they could run all the time but only report if they own the resource group. You also have advance event monitoring within HACMP that could spawn a report based on an event in real time. On 4/27/06, Kauffman, Tom <KauffmanT at nibco.com> wrote: I need to split the monitoring for SAP and Oracle from the monitoring of the host it runs on -- because, in an IBM HACMP environment, the workload can move. So the oracle tests, *some* of the disk space tests, and *some* of the proc tests move from one box to another. So does the primary IP address. I need to be able to track 'colorado' the box (the hostname does NOT move) as well as 'colorado' the IP address. 'Colorado' the address could actually be pointing to the 'thames' or 'yukon' boxes. At which time, 'colorado' the box will be responding to the 'colorado-bt' adapter address (if 'colorado' the box is up at all). I can get some of what I want by running two clients, one for 'colorado' the box, and one for 'SAP' or some other such synthetic name. The biggest two challenges I see are splitting the OS filesystems from the application filesystems for freespace reporting, and the shifting IP address. I may have an 'out' on the IP address in the future, if I can migrate to what IBM calls 'aliasing' -- where they add the running address as a second address on the adapter and respond to both. And to make this a bit more fun, I have THREE of these silly environments to work with. Henrik, is there any way to hang two different IP addresses on the same bb-host entry such that the network connectivity test will be happy if either one responds? They are always on the same IP network, just different host addresses (our convention is to add 100 to the last octet to get the boot-time address for the matching run-time address). Is anyone else doing something silly like this?

Now that I think about it, I might have put group-except code in there, but I'll have to check... Bb-hostedit doesn't freak when it sees comments, however when it rewrites your bb-hosts file, your comments will magically disappear. I could fix this, but the ROI for me would be neglible, since we don't use comments. Yeah, I think the sourceforge mailing list is broken, but I don't know why and havent had time to fix it. I'm getting close to releasing devmon v0.2 though.

Erm, it wasn't so much as a patch as a botch so it wouldn't complain on seeing group-except. I didn't add it as a separate option as there is for group-only. I probably should do this properly sometime although its quite low on my list until I get a windows only admin wanting to use it. Mine doesn't actually have any comments in it but you're readme about bb-hostedit does say it would be wise not to include them so I thought I'd warn people about that.

http://www.nerdvana.org/eric/bbtools/ Its here along with some other useful utils. I think I edited it for group-except or one of the others as it didn't work correctly otherwise when there tags were present. It doesn't like comments either. Hope this helps!

Weird. Using the -Ae flag doesn't make a difference in time for me, nor does using sudo (this is testing it by hand, not from within hobbit). Still, it seems like you are doing better than we are. I wonder if this is a Fedora-specific peculiararity? I'll try installing fping on my wimpy Arch Linux desktop box and seeing if I can glean anything conclusive (although the difference in hardware is going to make this difficult). Thanks for sharing! -Eric

If you ping all the hosts in paralell (aka all ICMP replies are sent near simultaenously) then your test latentcy should really only be limited by the speed of your cpu as well as that of your network, not by how many hosts you are pinging. > I don't think this is "geometric" but linear.

I originally thought this might be part of the problem, so I wrote a script that went through the fping output and only included IP addresses that had < 10ms response time, which was over 95% of the addresses from the original list. Running fping again on this new list didn't change the behaviour much. It was still taking ~35 seconds to poll 1300 devices. > What is your ping interval?

Our poll interval is 60 seconds; its true that we do have room for growth, but at the rate that we are adding devices, we won't be able to grow much longer without exceeding the poll interval :) I'm just hoping for an 'easy' fix to fping that will make everything better. -Eric
